Conduct code reviews and mentor junior engineers. Proactively identify opportunities to modernize systems and improve engineering standards. Evaluate and leverage AI tooling to improve development efficiency and product capabilities. Required Qualifications Bachelor’s degree in Computer Science, Software Engineering, or related field (or equivalent experience). 4–6+ years of professional software engineering experience. Experience working across both front-end and back-end systems. Strong experience with: React (required for front-end contributions) RESTful APIs Backend experience in one or more of: Ruby (preferred) Elixir (preferred) Java Experience with relational databases (MySQL or similar).

Interest in building scalable systems that evolve over time. #J-18808-Ljbffr
